Title: Identifying system for rising method of processor
Inventor: SHODA MITSUAKI
IPC: G06F15/177
Filed: 1987-01-24
Abstract: PURPOSE:To realize the automatic identification of the rising method of each processor and to improve the operability with processors, by adding a constitution information storing device to those processors. CONSTITUTION:The processors 20-2n reads the processor constitution information out of a constitution information storing device 1 in the rising state of each processor. If the processor constitution information is kept in an initial state, it is regarded that all processors rise simultaneously and a normal operation is carried out. If the processor constitution information is not kept under an initial state, a set-in rising operation is carried out with its own processor cut off and a normal rising operation is carried out with its own processor kept under an operation state with reference to a part of its own processor corresponding to identifiers C0-Cn in an operation state column (d). A master processor 20 cuts off a processor having no rise and produces the processor constitution information to write it into the device 1. Thus it is possible to automatically identify the rising way of each processor with no intervention of manual operations.

Filed: 1988-01-26
Abstract: PURPOSE:To reduce the exhaust emission by immediately starting the closed- loop-control by a downstream side air-fuel ratio sensor when other closed-loop- condition is fulfilled when the duration time of the operation state other than a theoretical air-fuel ratio is shorter than a prescribed time, while by starting the closed-loop-control after the lapse of a prescribed delay time, when the duration time is longer. CONSTITUTION:An operation state judging means judges the operation state other than a theoretical air-fuel ratio, for example, the fuel cut state, and when a judging means judges that the continuation time is shorter than a prescribed time, a downstream side F/B judging means judges the closed-loop-condition, and then the closed-loop-control by a downstream side O2 sensor is started immediately. A calculation means calculates the air-fuel ratio feedback control constants (skip quantity) RSR and RSL, and further calculates the air-fuel ratio correction quantity FAF according to the output of an upstream side O2 sensor for a three-component catalyst CCRO, and adjusts the air-fuel ratio. When the duration time is long, a delay means performs delaying for a prescribed time, and closed-loop control is started. Therefore, the reduction of exhaust emission and improvement of fuel consumption are permitted.

IPC: H04J11/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of interference/compensation functions by controlling the sampling timing of an identification signal becoming the reference of the extraction of an error signal with the output result of a lock phase detection circuit and shifting the phase of a sampling clock. SOLUTION: The demodulated base band signal of an H-polarized wave is inputted to the cross polarized wave interference/compensation circuit 20 of a V-polarized wave-side through a cable 40 after it is converted into a digital signal by A/D conversion circuits 901 and 902. The sampling clock in the A/D conversion circuits 901 and 902 are generated into optimum phase control signals in a clock phase detector 801 based on digital data after A/D conversion. A clock phase adjustment circuit 802 phase-shifts the phase of the reproduced clock CK1 from the oscillator 30 of the V-polarized wave-side based on the control signals and controls the sample timing of the input analog signal of the cross polarized wave interference/compensation circuit 20. Thus, the maximum interference/compensation functions can be brought out.

Title: Apparatus for detecting angular displacement value and velocity value of angular displacement
Inventor: OKAMOTO KENJI
IPC: G01P3/42
Filed: 1984-01-27
Abstract: PURPOSE:To detect an angular displacement value and the velocity of an angular displacement simply and quickly as digital value by processing potentials of a potentiometer in the rotary displacement at an extremely small time difference. CONSTITUTION:For example, output voltage of a potentiometer P mounted on a manipulator joint of a robot is amplified and inputted into sample holding circuits SH1 and SH2. Output of the circuit SH1 is converted into digital from analog and inputted into a register circuit RE1. Difference between the output of the circuit SH2 and that of the circuit SH1 is converted into digital from analog and inputted into a register circuit RE2. Inputs into the circuits SH1 and SH2 are controlled with a timer element of a signal generation logic circuit SL. In this manner, two potentials as intact and a value as difference therebetween are inputted separately into the two circuits SH1 and SH2 at a extremely small time difference to detect the angular displacement position and the velocity of angular displacement by computation. Thus, the joint angle and velocity of the manipulator can be detected simultaneously with a simple circuit at a short time interval.

Title: Magnetic recording medium
Inventor: INAMI HIROO
IPC: C09D175/06
Filed: 1989-01-25
Abstract: PURPOSE:To obtain both of excellent video characteristics and audio characteristics by specifying tapping densities of magnetic material used for a first magnetic layer and another second magnetic layer, making the tapping density of the magnetic material for the first magnetic layer larger than that of the magnetic material for the second magnetic layer, and specifying the difference between these densities. CONSTITUTION:The tapping density of the magnetic material used for the first magnetic layer is specified from 0.8 to 1.0 and that of the material for the second magnetic layer is specified from 0.7 to 0.9. Moreover, the tapping density of the material for the first layer is made larger than that of the magnetic material for the second layer by a difference >=0.02. When a magnetic material is subjected to compacting treatment under too large pressure in order to increase the tapping density, acicular magnetic material is broken and acicular ratio thereof is lowered. A magnetic tape using these material has low aspect radio and coercive force, and consequently inferior video characteristics. However, by controlling the tapping densities of the first and second layers in respective specific ranges in the process of compacting under pressure, the medium having a high compacting ratio with both of the satisfied video and audio characteristics is resulted.

Title: Information reproducing apparatus
Inventor: IMAI MITSUGI
IPC: H04L1/00
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To realize a stable PLL operation by generating a phase error signal using each reproduced signal or a part of it in the first to fourth detection timings. SOLUTION: PEC 137 selectively uses phase error signals PEI to PE3 and phase offset signal to generate a phase error signal for VCO. A subtractor 311 subtracts the selected phase offset Pos from the selected phase error signals PEs to provide an output of the phase error signal PE. This phase error signal is supplied to VCO via the D/A converter and loop filter in order to control the oscillation frequency. Thereby, the reproducing system, even if it provides a comparatively large waveform distortion of the reproduced signal, can calculate adequate phase error in view of preventing malfunction of PLL and resultant distortion of clock and improving the reproduction performance.
